Deep Silver today issued an essential utility for fans seeking to survive the upcoming Metro: Last Light. The first video released in a series of three, the survival guide prepares players for their service in the Spartan Order, the self-styled protectors of the Metro.

The vid, seen above, familiarizes would-be Rangers with the dangers they will face within the different areas of post-apocalyptic Moscow: the tunnels of the Metro, the ravaged surface wasteland and the deadly transition levels in between. Each zone harbours its own dreadful hazards, be it human enemies from hostile, warring factions, abhorrent mutants or the toxic environment itself. Designed to prepare Rangers for their mission to protect the survivors in the Metro, Deep Silver says this guide is the ultimate support tool in the struggle for existence within the terrifying world of Metro: Last Light.
